How to use Microsoft Edge's reading features in Windows 10 April 2018 Update

Microsoft Edge can replace your PDF and EPUB reader apps, and it can improve your web reading experience. In this guide, we show you how.
On Windows 10, Microsoft Edge has included a reading experience for PDF documents, EPUB ebooks, and web pages using Reading view for quite a while. But starting with the April 2018 Update (version 1803) the experience is getting updated with various improvements and a new interface.
In the updated version of Edge, which continues the work from previous versions, you'll find an interface that uses Fluent Design elements for a more consistent experience, whether you're reading an ebook or web page, or filling out a form online. Also, there are some new tools and features that will be available depending on the content you're viewing.
